What is the difference between us and those who past already and between those who are going to

What is the difference between us and those who past already and between those who are going to come??? Best people of past or common all are same now....Same feelings,emotions,cry,happiness,smile,laugh, drink,eat, die ...all have best technologies of their time and will be in future for future generation.......whats different we are doing in this world from day one????? Nothing, everything is same only humanity is getting more dramatic... I need to spend my life differently but how???.....best formula is to learn from other mistakes and experiences to stay ahead and to spend a faithful/honest/happy life with everyone rather than to be bad/lusty....we have to learn from past.mistakes
